Bakeware, Tableware, Drinkware and Cookware Design Keep Warm Coaster by Elkan Nuri This product performs its function in its simplest form. This product is designed in golden ratio. Fire circles are the inspiration source of this design. The product is only formed in circle lines. The product is recommended to use with mugs. It's used with standard small candles. The organic holes on the product have taken on the coolness of the metal to provide a fresher look. The product looks very simple but every line is extremely rational. It looks modest from natural materials. The designer has done it with his own hands without needing a manufacturer.
